Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465252, here are decompositions:

29 + 31465223 = 31465252
59 + 31465193 = 31465252
191 + 31465061 = 31465252
311 + 31464941 = 31465252
431 + 31464821 = 31465252
443 + 31464809 = 31465252
521 + 31464731 = 31465252
743 + 31464509 = 31465252

Showing the first eight; more decompositions exist.
